Implantation Cramping???

Kelly • Married. 4 years TTC #1. VA🍍. PCOS.
Can anyone share their experiences with implantation? Preferably stories ending with a BFP. When did it first happen? What did it feel like? 3/4 DPO & feeling the WEIRDEST little twinges of pinching. Not "painful" persay just coming and going on my
left side (where I felt OV occur this month - don't know if that matters). Thanks!
